[PyMOL] How to label atom at proper positions?

[sunyeping <sun...@al...>]

Dear pymol users,

I select a series of CA atoms in a structure in pymol and show them as sphere in pymol and want to label them. If using the label menu at the up-right conner of pymol, the labels shown overlaps with spheres and can not be seen. So I wish to show the labels at a bit distance from the seleccted atoms. Is there a method to do that? I will appreciate to any help! 

Best regards
